Iranian President Hassan Rouhani arrives Monday in Italy, beginning his first European tour since a nuclear deal saw sanctions lifted against the Islamic Republic.

The visit, whose chief aim is to boost economic ties and which will see Rouhani visit France later this week, had been planned for last November but was cancelled after the deadly Takfiri attacks in Paris.

The three-day trip comes a week after Tehran's deal with world powers came into force, allowing the United States and the European Union to lift economic sanctions in exchange for Tehran curbing its nuclear activities.

Tehran said Sunday it will buy 114 Airbus planes to revitalize flag carrier Iran Air's ageing fleet -- the first major commercial deal since sanctions were lifted -- and the deal is expected to be signed during the Paris leg of the visit.

The Iranian leader has hailed the agreement as a "new chapter" for Iran as its economy returns to global markets.

After a working lunch with his Italian counterpart Sergio Mattarella, Rouhani will meet Prime Minister Matteo Renzi.

He is also to meet Pope Francis at the Vatican, in the first official visit by an Iranian president there since Mohammad Khatami in 1999.

Heading a high-powered business delegation, Rouhani is also to speak at an economic forum.

Since 2012, trade between Iran and Italy has slumped from 7 billion euros (around $7.6 billion) to 1.2 billion euros a year.

But now sanctions have been lifted, Italian businessmen are eager to renew ties.

"Italy was Iran's leading economic and trade partner before the sanctions," Italian economic development minister Federica Guidi said a few months ago, seeking to ensure her country regains that position.

Fifty-eight percent of Italy's exports to Iran are in the mechanics sector, followed by chemical products at eight percent.
